> Have you compared the sites where Astra-Zeneca played fast and loose with its vaccine experiments, and the occurence of the more contagious mutations after on a map? Correlation does not imply causation. Vaccine makers prefer to test in regions with high infection activity because statistically significant results can be obtained faster. And mutations are more likely to occur in regions with high infection activity because mutations are a numbers game. Most likely we're just seeing two effects with the same root cause, without those two effects being causally linked.
